Paul mixed 5 quarts of dry ingredients and 2 quarts of water to make a batch of concrete. he ran out of the mixture before finishing his project, so he made another batch using 15 quarts of dry ingredients

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
